Our Veterinarians

Dr Andrew Mast
Dr. Andrew Mast, DVM
Owner & Veterinarian

A Grantsville native, Dr. Andrew Mast earned his Doctor of Veterinary Medicine from the Virginia-Maryland College of Veterinary Medicine in 2018. Growing up on his family’s dairy farm inspired a lifelong passion for animal health and agriculture. He has special interests in large and small animal medicine, reproduction and ultrasound.

Dr. Mast and his wife, Rebecca, have a family of four children along with a dog, a cat, and a backyard flock of chickens. When he’s not caring for animals, you’ll find him helping on the farm, tackling home projects, or playing volleyball. Dr. Mast is blessed to be able to serve his hometown and enjoys reconnecting with familiar faces while building new bonds with local families.

Dr Garrett Call
Dr. Garrett Call, DVM

Associate Veterinarian

Dr. Garrett Call brings a wealth of knowledge and rural experience to Casselman Veterinary Services. He earned his veterinary degree from Tufts Cummings School of Veterinary Medicine and enjoys the dynamic nature of mixed animal practice, where no two days are ever the same.

Raised in rural Kansas, Dr. Call thrives in the hands-on environment of both in-clinic care and on-farm visits. His veterinary interests include surgery and general medicine for animals, large and small. Outside of work, he’s a devoted family man who loves attending his children’s events, traveling, and enjoying time with his wife and their lively collection of animals (chickens, cats, and dogs).
